Groundwater is detected using a portable electronic device. The unit measures the electrical properties of the earth and produces a profile showing the structure of the ground, showing rock layers, fault zones and areas that are best for the drilling of boreholes.
A clear break between dolerite intrusions shows a water source at stations 16/17, 105m below the surface.
A survey over the surface is done and the following image of the subsurface is produced. The next image is a virtual 3D image of the surface trace of the water-bearing structure showing the best place to drill for water.
